Abstract: The present disclosure relates to a SDN-based method for mirroring packets, wherein a SDN controller is coupled to an upper layer application and at least one data switching exchange respectively, and the method including: a) the upper layer application sends a mirroring instruction to the SDN controller through a first northbound interface of the SDN controller; b) the SDN controller generates a second flow table based on the mirroring instruction and a first flow table sent by a first data switching exchange; wherein the first data switching exchange initiates transmission of the packets, the first flow table encapsulates the packets, and the second flow table includes at least an action command corresponding to the mirroring instruction; and c) a second data switching exchange extracts the packets from the second flow table, and mirrors the packets to the designated node based on the action command.
